As a social engineer, you spend all of your time manipulating people’s brains.  Yet most of the social engineers I meet don’t know the difference between the amygdala and the cerebral cortex.

And you need to.

So this article is going to give you a quick trip through the human brain. 

The brain isn’t just a single organism – it’s truly a three-part entity known as the triune brain.  The idea of the triune brain was first proposed by Paul MacLean. He proposed that the brain that you and your caveman ancestors shared is not a single brain but actually a three part structure.  MacLean viewed our brains as similar to "three interconnected biological computers, [each] with its own special intelligence, its own subjectivity, its own sense of time and space and its own memory.”  That is, while each of the three brains interacts, each one functions as a separate and somewhat independent unit.
